...Bar Harbor Observation Not Available...
We are aware that the current weather observation at the Bar Harbor airport is not going out on the web, and a lot of people want to know what's going on there. This weather station is not under the control of NWS Caribou. We are aware there is a fiber upgrade going on at the Bar Harbor airport, and this is why the observation is not available. We do not know of a restoration time.
As an alternate, we do create observation maps every hour at https://www.weather.gov/car/observations . You can change the parameter in the tabs at the top. Also, you can see a text listing of current observations around the region at https://forecast.weather.gov/product.php?site=NWS&issuedby=GYX&product=RWR&format=CI&version=1&glossary=1&highlight=off .
